CVE-2023-50387 8 Fedoraproject, Isc, Microsoft and 5 more 18 Fedora, Bind, Windows Server 2008 and 15 more 2025-05-12 7.5 High
Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records.
CVE-2017-7557 1 Powerdns 1 Dnsdist 2025-04-20 N/A
dnsdist version 1.1.0 is vulnerable to a flaw in authentication mechanism for REST API potentially allowing CSRF attack.
CVE-2015-5311 1 Powerdns 1 Authoritative 2025-04-12 N/A
PowerDNS (aka pdns) Authoritative Server 3.4.4 before 3.4.7 allows remote attackers to cause a denial of service (assertion failure and server crash) via crafted query packets.
CVE-2016-5426 1 Powerdns 1 Authoritative 2025-04-12 N/A
PowerDNS (aka pdns) Authoritative Server before 3.4.10 allows remote attackers to cause a denial of service (backend CPU consumption) via a long qname.
CVE-2015-1868 2 Fedoraproject, Powerdns 3 Fedora, Authoritative, Recursor 2025-04-12 N/A
The label decompression functionality in PowerDNS Recursor 3.5.x, 3.6.x before 3.6.3, and 3.7.x before 3.7.2 and Authoritative (Auth) Server 3.2.x, 3.3.x before 3.3.2, and 3.4.x before 3.4.4 allows remote attackers to cause a denial of service (CPU consumption or crash) via a request with a name that refers to itself.
CVE-2014-8601 2 Debian, Powerdns 2 Debian Linux, Recursor 2025-04-12 N/A
PowerDNS Recursor before 3.6.2 does not limit delegation chaining, which allows remote attackers to cause a denial of service ("performance degradations") via a large or infinite number of referrals, as demonstrated by resolving domains hosted by ezdns.it.
CVE-2016-6172 2 Opensuse, Powerdns 3 Leap, Opensuse, Authoritative Server 2025-04-12 N/A
PowerDNS (aka pdns) Authoritative Server before 4.0.1 allows remote primary DNS servers to cause a denial of service (memory exhaustion and secondary DNS server crash) via a large (1) AXFR or (2) IXFR response.
CVE-2015-5470 1 Powerdns 2 Authoritative, Recursor 2025-04-12 N/A
The label decompression functionality in PowerDNS Recursor before 3.6.4 and 3.7.x before 3.7.3 and Authoritative (Auth) Server before 3.3.3 and 3.4.x before 3.4.5 allows remote attackers to cause a denial of service (CPU consumption or crash) via a request with a long name that refers to itself. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1868.
CVE-2014-3614 1 Powerdns 1 Powerdns Recursor 2025-04-12 N/A
Unspecified vulnerability in PowerDNS Recursor (aka pdns_recursor) 3.6.x before 3.6.1 allows remote attackers to cause a denial of service (crash) via an unknown sequence of malformed packets.
CVE-2016-5427 1 Powerdns 1 Authoritative 2025-04-12 N/A
PowerDNS (aka pdns) Authoritative Server before 3.4.10 does not properly handle a . (dot) inside labels, which allows remote attackers to cause a denial of service (backend CPU consumption) via a crafted DNS query.
CVE-2012-0206 1 Powerdns 1 Authoritative Server 2025-04-11 N/A
common_startup.cc in PowerDNS (aka pdns) Authoritative Server before 2.9.22.5 and 3.x before 3.0.1 allows remote attackers to cause a denial of service (packet loop) via a crafted UDP DNS response.
CVE-2012-1193 1 Powerdns 1 Powerdns Recursor 2025-04-11 N/A
The resolver in PowerDNS Recursor (aka pdns_recursor) 3.3 overwrites cached server names and TTL values in NS records during the processing of a response to an A record query, which allows remote attackers to trigger continued resolvability of revoked domain names via a "ghost domain names" attack.
CVE-2008-3337 1 Powerdns 2 Authoritative Server, Powerdns 2025-04-09 N/A
PowerDNS Authoritative Server before 2.9.21.1 drops malformed queries, which might make it easier for remote attackers to poison DNS caches of other products running on other servers, a different issue than CVE-2008-1447 and CVE-2008-3217.
CVE-2009-4010 1 Powerdns 1 Recursor 2025-04-09 N/A
Unspecified vulnerability in PowerDNS Recursor before 3.1.7.2 allows remote attackers to spoof DNS data via crafted zones.
CVE-2008-1637 1 Powerdns 1 Recursor 2025-04-09 N/A
PowerDNS Recursor before 3.1.5 uses insufficient randomness to calculate (1) TRXID values and (2) UDP source port numbers, which makes it easier for remote attackers to poison a DNS cache, related to (a) algorithmic deficiencies in rand and random functions in external libraries, (b) use of a 32-bit seed value, and (c) choice of the time of day as the sole seeding information.
CVE-2006-4251 1 Powerdns 1 Recursor 2025-04-09 N/A
Buffer overflow in PowerDNS Recursor 3.1.3 and earlier might allow remote attackers to execute arbitrary code via a malformed TCP DNS query that prevents Recursor from properly calculating the TCP DNS query length.
CVE-2006-4252 1 Powerdns 1 Recursor 2025-04-09 N/A
PowerDNS Recursor 3.1.3 and earlier allows remote attackers to cause a denial of service (resource exhaustion and application crash) via a CNAME record with a zero TTL, which triggers an infinite loop.
CVE-2008-3217 1 Powerdns 1 Recursor 2025-04-09 N/A
PowerDNS Recursor before 3.1.6 does not always use the strongest random number generator for source port selection, which makes it easier for remote attack vectors to conduct DNS cache poisoning. NOTE: this is related to incomplete integration of security improvements associated with addressing CVE-2008-1637.
CVE-2009-4009 1 Powerdns 1 Recursor 2025-04-09 N/A
Buffer overflow in PowerDNS Recursor before 3.1.7.2 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via crafted packets.
CVE-2008-5277 1 Powerdns 1 Powerdns 2025-04-09 N/A
PowerDNS before 2.9.21.2 allows remote attackers to cause a denial of service (daemon crash) via a CH HINFO query.
